USGS Water-Year Summary 2025

07239700 NORTH CANADIAN RIVER NEAR YUKON, OK

LOCATION - Lat 35°32'22", long 97°44'32" referenced to North American Datum of 1927, in SW 1/4 SS 1/4 W 1/4 sec.04, T.12 N., R.5 W., Canadian County, OK, Hydrologic Unit 11100301, near left downstream end of bridge on new State Highway 4, 2.2 mi north of State Highway 66, 2.9 mi downstream from Shell Creek, and at mile 292.0.

DRAINAGE AREA - 13,456 mi² of which 3,497 mi² probably is noncontributing. From automated delineation using 10-meter National Elevation Dataset digital elevation model data dated 10/01/2006 and Watershed Boundary Dataset dated 10/01/2006, using Albers Equal-Area Projection, North American Datum 1983.

REVISIONS HISTORY - WSP 1341: Drainage area. WDR 2012: Drainage area.

SURFACE-WATER RECORDS

PERIOD OF RECORD - November 1943 to September 1999 (discharge measurements only), October 1999 to current year.

GAGE - Water-stage recorder. Datum of gage is 1247.66 ft above NAVD88.

REMARKS -

10/01/2023 - 9/30/2024: records fair.

Quality of data for other periods can be obtained by contacting the Oklahoma-Texas Water Science Center.

Some regulation by Fort Supply Lake (station 07236500) for period May 1942 to April 1948 and by Canton Lake (station 07238500) thereafter.

EXTREMES FOR PERIOD OF RECORD - Maximum discharge:, 25,100 ft³/s, August 21, 2007; Maximum gage-height 16.92 ft, August 21, 2007

WATER-QUALITY RECORDS

PERIOD OF RECORD -

WATER TEMPERATURE: November 1999 to current year. Data available prior to 10/01/2007 has been graded as unusable.

SPECIFIC CONDUCTANCE: November 1999 to current year. Data available prior to 10/01/2007 has been graded as unusable.

REMARKS -

Accuracy rating of the record for the 2024 Water Year:

WATER TEMPERATURE: Excellent; some deletions were applied. The data loss that occurred was not significant. The sensor underwent NIST checks on a quarterly basis, and one EWI, depth-integrated cross-section survey was completed within this water year.

SPECIFIC CONDUCTIVITY: Good; heavy spike deletions and multiple data gaps occurred. Fouling and calibration drift corrections were required throughout the year. One EWI, depth-integrated cross-section survey was completed within this water year.

Heavy spiking for specific conductivity occurred throughout this period. Values have been analyzed to the best of our ability to differentiate between what are spikes vs. what are reasonable/valuable data points.

Quality of data for other periods can be obtained by contacting the Oklahoma-Texas Water Science Center.
